Secure communication using physical proximity

ABSTRACT

Systems and methods may provide for implementing a secure communication using physical proximity. In one example, the method may include transmitting an encrypted first communication including a sensitive information file, decrypting the encrypted first communication to generate a decrypted first communication including the sensitive information file, displaying the decrypted first communication, capturing a version of the decrypted first communication displayed on the intermediary device, and extracting the sensitive information file at a user device.

BACKGROUND

1. Technical Field

Embodiments generally relate to secure communications. More particularly, embodiments relate to implementing a secure communication using physical proximity.

2. Discussion

Mobile device payment services may utilize a received confidential communication, such as a quick response (QR) code, to enhance security. A QR code may contain information necessary for the mobile device to complete a transaction, which may be extracted by scanning the code with, for example, a camera device.

However, one disadvantage to using a QR code may be that there is no assurance that its use will be limited to the intended user. For example, malware running on the computer device may capture a screenshot of the QR code, thereby allowing its use by “bad actors” located remotely.

The arrangement and numbering of blocks depicted in FIG. 1 is not intended to imply an order of operations to the exclusion of other possibilities. Those of skill in the art will appreciate that the foregoing systems and methods are susceptible of various modifications and alterations.

Turning now to FIG. 2, a flowchart of an example of a method of implementing secure communication using physical proximity in accordance with an embodiment of the invention is shown. In this example, a user, possessing a user device, such as the third user device 500 (FIG. 1), may utilize an intermediary device, such as the intermediary device 200 (FIG. 1.), to request a URL (relating to an information store of interest to the user) from a vendor utilizing a transmitting device 100, such as the transmitting device 100 (FIG. 1).

The method might be implemented as a set of logic instructions stored in a machine- or computer-readable storage medium such as random access memory (RAM), read only memory (ROM), programmable ROM (PROM), firmware, flash memory, etc., in configurable logic such as programmable logic arrays (PLAs), field programmable gate arrays (FPGAs), complex programmable logic devices (CPLDs), in fixed-functionality logic hardware using circuit technology such as application specific integrated circuit (ASIC), complementary metal oxide semiconductor (CMOS) or transistor-transistor logic (TTL) technology, or any combination thereof. For example, computer program code to carry out operations shown in the method may be written in any combination of one or more programming languages, including an object oriented programming language such as Java, Smalltalk, C++ or the like and conventional procedural programming languages, such as the “C” programming language or similar programming languages.

The process may begin at processing block 2000. At processing block 2010, the user may utilize the intermediary device to transmit a request communication to the transmitting device to provide a secure communication including an URL directed to an information store of sensitive information of interest to the user. At processing block 2020, the transmitting device may transmit a confidential communication, such as the third confidential communication 106 (FIG. 1). The confidential communication may include a confidential communication pattern, a confidential communication encryption key, and a URL directed to the information store of sensitive information of interest to the user. The confidential communication may be encrypted using, for example, the confidential communication encryption key.

At processing block 2030, the intermediary device may receive the confidential communication. In particular, the confidential communication may pass through, for example, an intermediary device memory component, such as the intermediary device memory component 202 (FIG. 1) and an intermediary device graphics memory, such as the intermediary device graphics memory 206 (FIG. 1). The confidential communication may remain encrypted.

The intermediary device security component may decrypt the confidential communication, and generate a modified confidential communication, such as the modified third confidential communication 210 (FIG. 1), including a modified confidential communication pattern, a modified confidential communication encryption key, and a modified confidential communication URL. The modified confidential communication may be encrypted. At processing block 2050, the intermediary device may display the encrypted modified confidential communication on an intermediary device interface, such as the intermediary device interface 213 (FIG. 1).

At processing block 2060, the user, who is proximately located to the intermediary device, may utilize a user device camera, such as the third user device camera 503 (FIG. 1), to capture an image file of the encrypted modified confidential communication, such as the third user device sensitive information file 505 (FIG. 1), displayed on the intermediary device interface. At processing block 2070, a user device security component, such as the third user device security component 506 (FIG. 1), may be utilized to decrypt and extract information from the image file of the encrypted modified confidential communication. More specifically, the user device security component may be configured to extract the modified confidential communication URL utilizing the modified code encryption key. Accordingly, a secure output configuration based on an end-to-end encrypted channel between the transmitting device, the intermediary device (i.e., the intermediary device security component), and the user device (i.e., the user device security component) may be implemented utilizing physical proximity.

At processing block 2080, the user may select the URL to retrieve the sensitive information of interest to the user located at the transmitting device. At processing 2090, upon receiving this request, the transmitting device may recognize that the request is from a user device that has received (and decrypted) a communication from the intermediary device, thereby indicating that the user device is a secure destination to transmit the information store of interest to the user. At processing block 2100, the transmitting device may transmit the information of interest to the user to the user device. At processing block 2110, an user device may receive the information of interest to the user, and may display it on the user device interface, such as the third user device interface 502 (FIG. 1) for the user. At processing block 2120, the process may terminate.

Examples of hardware elements may include processors, microprocessors, circuit elements (e.g., transistors, resistors, capacitors, inductors, and so forth), integrated circuits, application specific integrated circuits (ASIC), programmable logic devices (PLD), digital signal processors (DSP), field programmable gate array (FPGA), logic gates, registers, semiconductor device, chips, microchips, chip sets, and so forth. Examples of software may include software components, programs, applications, computer programs, application programs, system programs, machine programs, operating system software, middleware, firmware, software modules, routines, subroutines, functions, methods, procedures, software interfaces, application program interfaces (API), instruction sets, computing code, computer code, code segments, computer code segments, words, values, symbols, or any combination thereof. Determining whether an embodiment is implemented using hardware elements and/or software elements may vary in accordance with any number of factors, such as desired computational rate, power levels, heat tolerances, processing cycle budget, input data rates, output data rates, memory resources, data bus speeds and other design or performance constraints.

One or more aspects of at least one embodiment may be implemented by representative instructions stored on a machine-readable medium which represents various logic within the processor, which when read by a machine causes the machine to fabricate logic to perform the techniques described herein. Such representations, known as “IP cores” may be stored on a tangible, machine readable medium and supplied to various customers or manufacturing facilities to load into the fabrication machines that actually make the logic or processor.

Techniques described herein may therefore provide a feed-forward system that ensures both real-time operation of the consumer video pipeline and dynamic updating of the operating pipeline to deliver optimal visual perceptual quality and viewing experience. In particular, a discrete control system for the video pipeline can dynamically adapt operating points in order to optimize a global configuration of interactive component modules that are related to video perceptual quality. In a series configuration, the perceptual quality analysis module may be placed before the video processing pipeline and parameters determined for the post-processing pipeline may be used for the same frame. In the case of distributed computation of the quality analysis block or when perceptual quality analysis needs to be performed at intermediate points in the pipeline, the parameters determined using a given frame may be applied on the next frame to ensure real-time operation. Distributed computation is sometimes beneficial in reducing complexity as certain elements for perceptual quality computation may already be computed in the post-processing pipeline and can be re-used. Illustrated approaches may also be compatible with closed-loop control where the perceptual quality analysis is re-used at the output of the video processing pipeline to estimate output quality, which is also used by the control mechanism.

Embodiments of the present invention are applicable for use with all types of semiconductor integrated circuit (“IC”) chips. Examples of these IC chips include but are not limited to processors, controllers, chipset components, programmable logic arrays (PLAs), memory chips, network chips, and the like. In addition, in some of the drawings, signal conductor lines are represented with lines. Some may be different, to indicate more constituent signal paths, have a number label, to indicate a number of constituent signal paths, and/or have arrows at one or more ends, to indicate primary information flow direction. This, however, should not be construed in a limiting manner. Rather, such added detail may be used in connection with one or more exemplary embodiments to facilitate easier understanding of a circuit. Any represented signal lines, whether or not having additional information, may actually comprise one or more signals that may travel in multiple directions and may be implemented with any suitable type of signal scheme, e.g., digital or analog lines implemented with differential pairs, optical fiber lines, and/or single-ended lines.

Example sizes/models/values/ranges may have been given, although embodiments of the present invention are not limited to the same. As manufacturing techniques (e.g., photolithography) mature over time, it is expected that devices of smaller size could be manufactured. In addition, well known power/ground connections to IC chips and other components may or may not be shown within the figures, for simplicity of illustration and discussion, and so as not to obscure certain aspects of the embodiments of the invention. Further, arrangements may be shown in block diagram form in order to avoid obscuring embodiments of the invention, and also in view of the fact that specifics with respect to implementation of such block diagram arrangements are highly dependent upon the platform within which the embodiment is to be implemented, i.e., such specifics should be well within purview of one skilled in the art. Where specific details (e.g., circuits) are set forth in order to describe example embodiments of the invention, it should be apparent to one skilled in the art that embodiments of the invention can be practiced without, or with variation of, these specific details. The description is thus to be regarded as illustrative instead of limiting.

Some embodiments may be implemented, for example, using a machine or tangible computer-readable medium or article which may store an instruction or a set of instructions that, if executed by a machine, may cause the machine to perform a method and/or operations in accordance with the embodiments. Such a machine may include, for example, any suitable processing platform, computing platform, computing device, processing device, computing system, processing system, computer, processor, or the like, and may be implemented using any suitable combination of hardware and/or software. The machine-readable medium or article may include, for example, any suitable type of memory unit, memory device, memory article, memory medium, storage device, storage article, storage medium and/or storage unit, for example, memory, removable or non-removable media, erasable or non-erasable media, writeable or re-writeable media, digital or analog media, hard disk, floppy disk, Compact Disk Read Only Memory (CD-ROM), Compact Disk Recordable (CD-R), Compact Disk Rewriteable (CD-RW), optical disk, magnetic media, magneto-optical media, removable memory cards or disks, various types of Digital Versatile Disk (DVD), a tape, a cassette, or the like. The instructions may include any suitable type of code, such as source code, compiled code, interpreted code, executable code, static code, dynamic code, encrypted code, and the like, implemented using any suitable high-level, low-level, object-oriented, visual, compiled and/or interpreted programming language.

Unless specifically stated otherwise, it may be appreciated that turns such as “processing,” “computing,” “calculating,” “determining,” or the like, refer to the action and/or processes of a computer or computing system, or similar electronic computing device, that manipulates and/or transforms data represented as physical quantities (e.g., electronic) within the computing system's registers and/or memories into other data similarly represented as physical quantities within the computing system's memories, registers or other such information storage, transmission or display devices. The embodiments are not limited in this context.

The term “coupled” may be used herein to refer to any type of relationship, direct or indirect, between the components in question, and may apply to electrical, mechanical, fluid, optical, electromagnetic, electromechanical or other connections. In addition, the terms “first”, “second”, etc. may be used herein only to facilitate discussion, and carry no particular temporal or chronological significance unless otherwise indicated.

Those skilled in the art will appreciate from the foregoing description that the broad techniques of the embodiments of the present invention can be implemented in a variety of forms. Therefore, while the embodiments of this invention have been described in connection with particular examples thereof, the true scope of the embodiments of the invention should not be so limited since other modifications will become apparent to the skilled practitioner upon a study of the drawings, specification, and following claims.
